°
Answer:
When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object: T = mg.
Image result for I need help find how much tension is in the string???? And can you explain how you got it after you get the answer plz????
Hence, in such a case the tension will be equal to the centrifugal force.
Formula for tension = centrifugal force = mv2/r.
So the formula of tension will be = centripetal force – force of gravity = mv2/r – mg = m(v2/r-g)
The formula of tension will be = centripetal force + force of gravity = mv2/r + mg = m(v2/r+g)

Answer:
e. B and C
Explanation:
When the sun ignited in our solar system evaporation of the material closest to the sun took place. The low density material were pushed further. The rocks that remained formed the protoplanets. As, the early solar system was very hot parts of the protoplanets melted. This caused the melted material to flow towards the center of the planet. As the mass of the planet increases this causes more accretion which causes materials of different densities to mix.
The entire premises of this question infers to the concept of Creation. So the reason why the universe was created, in that sense, was so god could create a land to support the civilization he wanted.
